* startup/bspstart.c, start/start.S: setup BATs prior to attempting any
device access - missing BAT mappings were probably the reason for the
MMU malfunction assumption. Enabled MSR_DR.
PR 837/bsps
make sure exceptions_in_RAM flag is set prior to initializing exception
handling. Keep MCP disabled for memory probes :-( (the raven would
otherwise fault on PCI config space access to empty slots).

* startup/ldsegs.S: move CPU segment descriptor tables from .text to
.data; the CPU modifies the descriptor tables and this could be a
problem: a) if text segment is ever write-protected b) rtems-gdb-stub
checksums the text segment against the file gdb is using. A checksum
mismatch results because of the CPU touching the accessed bit...
PR 833/bsps
* irq/irq_asm.S: Currently, all (new exception) BSPs explicitely enable
the FPU across the user ISR but DONT save/restore the FPU context.
Any use of the FPU fron the user handler (e.g., due to GCC
optimizations) result in corruption. The fix results in an exception
in such cases (user ISR must explicitely save/enable/restore FPU).
